Linux Lab File Quota

All Linux Lab logins have a home directory where you can store your files.  There is a file quota of 500 MB for each user.  If the storage required for all of the files in your home directory reaches the file quota, you will have trouble using applications because new files won't get saved.

How to check your file quota

Your file storage quota is displayed in the MOTD app.  This can be found in the Application Menu under Accessories.

If you have a command line interface (for example, PuTTY), then you can use the command "quota -v".

How to Empty Trash

There may be large files in the Trash folder.  You can find this folder on your desktop or in the File Browser.  (The File Browser is found in the Application menu and System Tools submenu.)  Right-click on the Trash icon and select the Empty Trash option.
